To all whom it may concern:

Be it known thatl, ALFRED Srlniga citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented certain new and useful improvements in Presses, of which the following is a specification.-

My invention relates to improvements in presses, such as are adapted to be preferably maximally operated, for pressing paper or the like into suitable bales.

An important object of this invention is to provide a press of the above mentioned character, which is simple in construction, crmvenient in use, and quick and reliable in operation.

A further object of the invention is to provide a press of the above mentioned character, which is so constructed thatthe same may be quickly and easily filled with the material to be pressed, and the completed bale removed from the press, in. a similar manner.

A further object of this invention is to provide novel means to detachably lock the side or door of the baling chamber or casing in its closed position, such means being automatically operated'to hold the door in its closed position upon being moved to such closed position, and adapted to be readily manually operated to release the door.

A furtler object of the invention is to provide a press of the above mentioned character, so constructed that the pressing ele ment or follower will automatically gravitate to its starting position, upon the release of the operating shaft. v

Other objects andadvantages of this invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout'the same, Figure 1 is an elevation of the front longitudinal side of a hay press embodying my invention, Fig. 2 is an elevation of, the transverse side of the same, Fig. 3 is a plan view of the same, Fig. 1 is a horizontal section taken on line 4 4: of Fig. 1, Fig. 5 is an elevation of the front longitudinal side of the press, with the side or door removed, 1 6 is a longitudinal sectional view taken on line 6 6 of Fig. 1, Fig. 7 is a perspective view of the lower pressing member or follower, and, Fig. 8 is a side elevation of the means for turning-the operating shaft, a

removed.

In the drawings, wherein for the purpose .of illustration is shown a preferred embodiment of my invention, the numeral 10 designates a preferably vertical pressing or baling chamber or casing, having its rear longitudinal side closed by a longitudinal side part of such means being piece .11, which is permanently connected with transverse side pieces 12 forming a chamber or casing having its forward longi tudinal side 13 open, as shown. The transverse sides 12 diverge slightly forwardly,- as shown in Fig. 4, whereby the forward open side 13 is larger than the opposite closed side, thus enabling the bale to be quickly and easily removed,'as will be explained; The lower end of the baling chamber creasing 10 is closed by a stationary'bottom 14, which is rigidly connectedwith the lower portions of the longitudinal and transverse side pieces 11 and 12. Connected with the bottom I l are longitudinal beams or strips 15, which are mounted-upon transverse beams or strips 15, as shown. The open longitudinal side 13 is normally closed by a removable door or side 16, which is provided near its lower end with a transverse strip 17, rigidly connected therewith and extending beyond the same at both ends, to engage with the forward longitudinal edges of the transverse side pieces '12. The transverse strip 17 is arranged upon the exterior surface of the door 16, whereby the door passes inwardly between the transverse side pieces 12 and inwardly of a holding strip 18, rigidly connected with the transverse side pieces 12. It

is thusseen that the strips 17 and 18 serve as means to hold the lower end of the door 16 in its operative positlon, when moved thereto, and allow of the removal of the door when desired. Connected with the upper end of the removable door 16 is an upper transverse strip 19, extending at both ends beyond the door 16 and adapted'to engage with swinging holding dogs 20, pivoted upon the transverse side pieces 12, as shown at 21. The dogs have their inner ends provided with heavy weights 22, ends thereof upwardly.

The numeral 23 designates fixed stops,

to swing the hooked disposed to engage with the weights '22, to

positively limit their downward movement. The hooked ends of the holding dogs 20 have their outer ends 24 so shaped or beveled that the same will be automatically forced downwardly when engaged by he transverse strip 19, whereby the holding dogs will automatically grip the strip 19. it is obvious that the holding dogs may be readily swung to release the strip 19 when desired.

Connected with he removable door 16 near and spaced from the upper transverse strip 19 are suitably stiff approximately shaped spring clamps 25, adapted to engage the cXter'c-r surfaces of the transve side pieces 12, serving to connect them with the door 16 and prevent such end pieces from bulging. also serve as guide means, when the door 1 is being moved to its closed position, such clamps however not interfering with the movement of the door, when the same is be ing placed in or removed from operative position.

The mineral 26 designates a to piece or head, closing the upper end of the baling casing or chamber 10. This top piece is hinged with the rear side piece 11 and reinforcing strips 11, as she .vn at 27, to be swung in a substantial vertical plane. The free edge of the top piece 26 is disposed adjacent and inwardly of the upper end of the door 16, and is partiallyoverlapped by said door, the top piece 26 swinging downwardly to assume position between and below the upper ends of the longitudinal and transverse side )lGCOS 11 and 12. gidly mounted upon the upper surface of the top piece 26 is a lug 28 ada ted to c gagethe upper end of the rear side piece 11 and reinforo ing strip 11, when the top piece 26 is swung to its open or upper position, to support the latter in such position.

The top piece 26 preferably includes transverse reinforcing strips 29, upon which are rigidly -mounted bearingsBO, through which is journaled a longitudinal operating shaft 3l,-as shown. The operating shaft 81 extends outwardly at both ends beyond the bearings 30 and the end pieces 12 and has spools 32 and rigidly connected therewith. Connected with these spools by means of eye-bolts or the like, are depending L): flexible elements, preferably chains the lower ends of which are attached to lj-bolts 36, carried by the free ends of longitudinal bar 37. This bar 3'? operates through longitudinal slots 38 formed in the transverse side pieces 12 and has a pressing me1nher or follower 39 connected therewith, as more clearly shown in Fig. 7. This follower is sli htly tapered to properly fit within the baling chamber. It is thus seen that by retating the operating shaft 31 the chains will be wound upon the spools and 83 whereby the follower 39 will be elevated or moved toward the coacting top piece or pressing member 26. The follower or pressing member 09 is provided with transverse grooves 39, which are in registration with longitudinal grooves 10', formed through the rear side piece 11, the upper end of the groores -10 being in registration with grooves 41 formed through the member 26. The tying wires are passed around the bale by being passed through the grooves 39, 4E0 and -11.

The spool 33 has a ratchet wneel 4-0 rigidly connected therewith, the same being preferably cast integral with the spool. T is ratchet wheel isengaged and turned by pawl 41, pivotally mounted within an operating head 12, comprising side )lates 1-3, which are apert-ured to rotatably receive the outer end of the spool The side )lates 43 are connected by transverse bolts and the pawl a1 is pivotally connected therewith by a transverse bolt At its outer end tie operating head 42 is provided with socket 4E6, having an operating lever 4 clamped therein. It is obvicu. that by ing the lever 4:6 up and down, the pawl 41 will intermittently rotate the shaft 31 in one direction, that to wind the chains upon the spools.

Big idly mounted upon the operating shaft 31' at the central portion thereof, is a holdg ratchet wheel -8, (see more particularly fig. (5), adapted to be engaged by a enacting on or pawl 4:9, formed upon a cured nd operated lever 50, pivotally connected 'ith the lug 28, as shown. The curved le- Jer automatically retains the tooth in engagement with the ratchet wheel. The teeth of the holding ratchet wheel 48 are so faced Lnat when they are engaged by the tooth or *1 4:9, the shaft 31 is prevented from ro tvting in the direction to allow the chains being unwound from the saools 32 and 33, but not interfering with the rotation of the shaft 31 in a reverse direction. it is obvious that by swinging the hand lever 50 in the proper direction, the tooth 49 will be moved out of engagement with the ratchet wheel 48 to release the shaft 31.

The operation of the apparatus is as follows: To till the baling chamber with material to be compressed, the door 16 is arranged in its operative position, to close. the op er. side 18 of the main casing. The top piece or pressing member 2!.- is now swung upwardly assume the outer position, where- 10 by the upper end of the casing or chamber 10 is entirely open to receive material to be compressed. The casing 10 having been. suitably filled with the material to be compi e d, the end piece or pressing element 26 swung downwardly. to assume its inner or the open side of the baling chamber and same and suitably compressed. one the desired pressure has been yflaccd upon. the material which is now in the form of a bale, the door 10 may be removed, wlereby the tying wires may be run around the bale, as is well known. The tooth i9 is new holding the shaft 531 against rotation, where v to move the bale, the lever 50 is swui. away from the ratchet wheel 48, so that the follower or pressing member 39 will. be free to gravitate .to its lower position. The top piece 26 will now be swung to the open position, if desired. The bale is easily removed from the casing 10 through the open si le'13 thereof, it being remembered that this side of the casing 10 is slightly wider than the closed side 11.

It is to be understood that the form of my invention herewith shown and described is to be taliena, a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of thoinvention or the scope of the subjoincd claims.
